文件写入：在完成的文件中显示Unicode字符？

Question

我正在尝试创建闪存卡来记住日语 kanji characters, and for that I'm crawling Jitenon，这是一个包含大量汉字定义、发音和含义的网站。我已经编写了类代码，其中包含可以在每个汉字页面上找到的相关信息，我目前正在尝试将我的汉字列表保存为 json 文件。

出于测试目的，我正在尝试像这样解析单个汉字对象：

...
var kanji = scraper.GetKanjiDefinition(kanjiUrl);
var jsonOptions = new JsonSerializerOptions() { WriteIndented = true };
var kanjiJson = JsonSerializer.Serialize(kanji, jsonOptions);
File.WriteAllText("kanji_json.json", kanjiJson, Encoding.UTF8);

这是我用相应的 json 序列化抓取的 example page：

{
  "Character": "\u697D",
  "MainRadical": "\u6728",
  "Strokes": 13,
  "KankenLevel": "\uFF19\u7D1A",

      "Yomi": 1,
      "MeaningIndices": [],

    },
    {
      "Reading": "\u304B\u306A\uFF08\u3067\u308B\uFF09",

    {

      "Yomi": 1,
      "MeaningIndices": [],
      "Education": "\u5C0F"
    }
  ]
}

我希望 json 文件中包含实际的日语文本，例如 "Character": "楽" 和 "MainRadical": "木" 以及 "KankenLevel": "９級" 而不是转义的 Unicode 字符喜欢 \u697D。我如何在 .NET 中实现这一点？

如果有什么不同，我在 Ubuntu 20.04 LTS 上，我在 VS Code 1.56.2 中打开我的 json 文件。

Answer 1

在您的 jsonOptions 中设置 Encoder：

var jsonOptions = new JsonSerializerOptions() { 
    Encoder = JavaScriptEncoder.Create(UnicodeRanges.All),
    WriteIndented = true 
};

上面的允许所有UnicodeRanges
